Purpose: This study examined the impact of traumatic brain injury (TBI) on self-perceived hearing and suprathreshold binaural processing in young and middle-age adults. Method: Ninety-three adults with normal hearing (thresholds [less than or equal to] 25 dB HL, 250-4000 Hz) participated in one of four groups: 38 young adults, 23 young adults with…

Background: Functional independence represents a key outcome for individuals with traumatic brain injury (TBI). The burden of TBI on people of color (POC) is evident when examining functional outcomes post-injury. Previous studies have described racial minority status as being associated with poorer functional outcomes. However, little is known…

Purpose: The Functional Assessment of Verbal Reasoning and Executive Strategies (FAVRES; MacDonald, 2005) test was designed for use by speech-language pathologists to assess verbal reasoning, complex comprehension, discourse, and executive skills during performance on a set of challenging and ecologically valid functional tasks. A recent French…

Monitoring the Future (MTF) is designed to give such attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been funded continuously…

The present volume presents new 2020 findings from the U.S. national Monitoring the Future (MTF) follow-up study concerning substance use among the nation's college students and adults from ages 19 through 60. This volume reports 2020 prevalence estimates on numerous illicit and licit substances, examines how substance use differs across this age…

Monitoring the Future (MTF) is designed to give attention to substance use among the nation's youth and adults. Since its onset in 1975, MTF has been funded continuously by the National Institute on Drug Abuse -- one of the National Institutes of Health -- under a series of peer-reviewed, competitive research grants. The 2020 survey, reported…

It is generally believed that brain injuries vary in their effects according to the age at which they are sustained, but the nature and extent of these differences remain elusive. A full enquiry requires, ideally, the study of strictly comparable lesions in the young and the old, the opportunity for follow-up examinations extending over decades in…

Information was collected on 95 people with mental retardation identified seven years previously as showing severe self-injurious behavior. Seventy-one percent were still showing severe self-injurious behavior. Self-injury status was predicted by a logistical regression model containing three variables: site of injury, reported stability of…
